Become a teacher if that's where your heart is. Fi doesn't lead us astray! You may want to try to get your certificate in more than one area if English positions are hard to find (could do Social Studies, History, Science, whatever as well). My boyfriend is a teacher and he LOVES it.
I've had several friends teach abroad, where there is great demand; you may want to consider doing that. They have had very good luck with obtaining jobs when they return, plus they get some pretty cool experiences to boot. :)
